What is the ratio of mass of electron to mass of proton
Mention the charges on electron and proton?​

Answer 1

Explanation:

A proton is a subatomic particle, symbol

A proton is a subatomic particle, symbol p

A proton is a subatomic particle, symbol p or

A proton is a subatomic particle, symbol p or p+

A proton is a subatomic particle, symbol p or p+, with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are collectively referred to as "nucleons" (particles present in atomic nuclei).

Answer 2

Explanation:

In physics, the proton-to-electron mass ratio, μ or β, is simply the rest mass of the proton (a baryon found in atoms) divided by that of the electron (a lepton found in atoms). Because this is a ratio of like-dimensioned physical quantities, it is a dimensionless quantity, a function of the dimensionless physical constants, and has numerical value independent of the system of units, namely:

μ = mp/me = 1836.15267343(11).[1]

The number enclosed in parentheses is the measurement uncertainty on the last two digits. The value of μ is known to about 0.1 parts per billion.
